Revision 1
      Add support for HDR metadata using the hdr_output_metadata connector property,
configure Dynamic Range and Mastering InfoFrame accordingly.

A drm_infoframe flag is added to dw_hdmi_plat_data that platform drivers
can use to signal when Dynamic Range and Mastering infoframes is supported.
This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version,
and only GXL support DRM InfoFrame.

The first patch add functionality to configure DRM InfoFrame based on the
hdr_output_metadata connector property.

The remaining patches sets the drm_infoframe flag on some SoCs supporting
Dynamic Range and Mastering InfoFrame.

Note that this was based on top of drm-misc-next and Neil Armstrong's
"drm/meson: Add support for HDMI2.0 YUV420 4k60" series at [1]
